Consider using color, profile images, or naming to create distinction.\n\nFor examples of the AAOS profile selection experience, see [Selecting a profile](/cars/design/automotive-os/product-experience/system-ui/profiles/how_profiles_work#selecting_a_profile).\n\nProfile lock best practices\n---------------------------\n\nWhen designing profile lock flows, it is best practice to:\n\n- **Offer multiple unlocking options**: Create options for users to unlock their profile via PIN, password, or pattern.\n- **Provide recovery flows** (see best practices below) for users who may forget their password, to help them avoid using AAOS in a 'guest' state.\n\nFor examples of the the AAOS profile lock experience, see [Locking a profile](/cars/design/automotive-os/product-experience/system-ui/profiles/how_profiles_work#locking_a_profile).\n\nProfile recovery best practices\n-------------------------------\n\nTo create a positive experience for users who have forgotten their profiles lock, you can:\n\n- **Provide alternative pathways forward**: If a user has forgotten their profile lock, you can give them the option to add a new profile so they can continue to use the car's infotainment system. To facilitate this, provide locked-out users an affordance to create a new Android user profile, create an alternate user profile, or choose to continue using a guest profile.\n- **Offer a pathway back to profile selection**: If a user arrives at the profile lock screen and can't remember their lock, they should still have a pathway to continue. Ideally, users can access a 'back' affordance to return to the profile selection screen, where they can then create a new profile or continue as a guest.\n\nGive users who've forgotten their password a pathway to back to profile selection"]]
